Upgrade Exchange 2007 on Windows 2003 to Windows 2008

We've got a single Exchange 2007 running in our Windows 2003 R2 domain. I'd
like to be able to rename the domain and know that I can't do this while
Exchange remains on the W2K3 server. Therefore I've got to make a
choice...upgrade the server to Windows 2008 and run rename or migrate
accounts/mailboxes to a new domain that's already named correctly. I'm
leaning toward the first option, but would appreciate input regarding
benefits/liabilities and any real-world experiences toward this end. Thanks.
